+This application can be launched from an IDE, or from a shell (linux, Windows, Mac). 
 You will need a config.json configuration file (see [default_config.json](https://github.com/Ahp06/SUMO_Emissions/blob/master/sumo_project/configs/default_config.json) for a template) and a simulation file.
 You can use your own scenario file (osm.sumocfg file), see : [SUMO Tutorials](http://sumo.dlr.de/wiki/Tutorials). 
 
 **With a Shell:**
 
-`> py ./emissions.py [-h] [-f CONFIGFILE] [-save] [-ref] [-steps STEPS]`

-* [-h] : Commands help 
-* [-f CONFIGFILE] : Choose your configuration file from your working directory
-* [-save] : Save the logs, by default logs will be in the logs file in the working directory with this format: 
-`sumo_project/logs/sumo_logs_{current_timestamp}.log`
-* [-ref] : Launch a reference simulation (without acting on infrastructure and vehicles
-* [-steps STEPS] : Choose the simulated time (in seconds) 
+Example :

+This command will create a new dump "dump1" with the configuration file "config" 
+and the simulation will be launched with CSV data export and logs backup.
 
-Ex : `> py ./emissions.py -f configs/your_config.json -save -ref`
